[2020] [Bug/Glitch]Can't Reconnect Controller on Xbox 1

Hello iF1am3z! I'm sorry to hear about this problem with your controller that you're experiencing in Rainbow Six Siege. I completely understand how this would be frustrating, and I truly apologize for the inconvenience that's been caused! Moving forward, please start by clearing your Xbox's cache. You can do this by unplugging your console from the wall, waiting at least two minutes, then plugging it back in. Afterward, please try completing the rest of our Xbox troubleshooting guide.

If the problem persists, can you please let me know if you've tried using the console wired? You can also contact our team on Facebook or Twitter, they'd be glad to continue providing assistance.
